Fan & Star, a website that delivers idol ranking information, launched a special event for the group GOT7 BamBam on the 28th. It is a celebratory advertising project for BamBam, who will release his first mini-album "riBBon" on the 15th of next month.

The success of BamBam's solo debut celebration project will be determined by the number of rainbow stars (points that can be collected on the site) donated by domestic and foreign fans. The more stars gathered the more celebratory advertisements are posted in many places.

When 20,000 stars are gathered, a congratulatory video will be shown on the CM board (square column) of Hapjeong Station in Seoul Subway. When the number of stars reaches 55,000, a congratulatory video will also be displayed on the Shinjuku Shin-Okubo electronic board in Tokyo, Japan. In addition, super-special gifts such as large digital electronic boards in Jamsil, M-Screen in Hongdae, and Seoul bus advertisements are waiting for fans.
